Quizplus · Accepted Answer

External validity refers to the generalizability of research findings to other populations, settings, and contexts. Ensuring external validity requires multiple strategies, including having a representative sample of participants (option A), selecting a setting that is similar to the larger population (option B), and replicating the study across multiple populations and settings (option C). Therefore, the best way to ensure external validity is through all the above options, which can help to enhance the generalizability of the research findings beyond the specific sample and context of the study.
